Field
7–0 Contains the duty value used to determine when a transition occurs on the PWM output signal. When a match occurs
DUTY with the corresponding PWMCNTn register, the PWM output toggles.
If DUTY equals 0x00, the PWMn output is always low (PPOLn=1) or always high (PPOLn=0). See
"PWM Boundary Cases"

24.2.12 PWM Shutdown Register (PWMSDN)

The PWM shutdown register provides emergency shutdown functionality of the PWM module. The
PWMSDN[7:1] bits are ignored if PWMSDN[SDNEN] is cleared.
